1. Deploy the kubeless helm chart on Opensshift


    To deploy the Kubeless Helm chart on an OpenShift cluster, we can use Pulumi's Kubernetes provider. First, ensure you have access to your OpenShift cluster and the kubectl command-line tool is configured to communicate with it.

    Kubeless is a Kubernetes-native serverless framework that allows you to deploy function code without worrying about the underlying infrastructure. To manage applications on Kubernetes with Pulumi, Helm charts are a convenient way to package applications and manage their deployment.

    We will use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource allows us to deploy Helm charts to a Kubernetes cluster.

    The following program in TypeScript deploys the Kubeless Helm chart on an OpenShift cluster:

    import * as k8s from "@pulumi/kubernetes"; // Define the settings for the Kubeless Helm chart. const kubelessChart = new k8s.helm.v3.Chart("kubeless", { // Specify the repository and name of the chart. chart: "kubeless", repo: "https://kubeless.io/kubeless", version: "1.0.7", // Replace with the desired version of Kubeless. namespace: "kubeless", // Specify the namespace where Kubeless will be installed. values: { // Custom values for the Kubeless chart can be provided here, if needed. }, // It's common practice to run OpenShift with RBAC enabled, so // you might need to adapt RBAC settings accordingly. transformations: [ (obj: any) => { // If the cluster uses RBAC and if required, modify object metadata here. // Example modification: Add labels or annotations. } ] }); // Export the resources created. export const chartName = kubelessChart.metadata.apply(metadata => metadata.name);

    This program does the following:

    • Imports the necessary Pulumi Kubernetes package.
    • Creates an instance of Chart, specifying the kubeless chart from its Helm repository.
    • Optionally, provides custom configuration values. In this example, no custom values are provided, but they can be included as needed.
    • Applies any necessary transformations for compatibility with your OpenShift cluster's configurations, which might include RBAC settings.

    To deploy this Helm chart to your OpenShift cluster using Pulumi:

    1. Save this code to a file named index.ts.
    2. Run pulumi up to deploy the changes. This will initiate the deployment of the Kubeless Helm chart to your OpenShift cluster.

    Please adjust the version number of the kubeless chart and the namespace as needed. Also, review the Helm chart's documentation for any particular settings that you might want to customize for your use case.
